LOOSE-LEAF 3300K OR BINDER.

T 0 a-ZZ whom t may cof/cern Be it known that I, GEORGE ALFRED BEN-Nn'r'r, a subject of the King of England, residing previously atQuatford, Curraweena Road, (iden Huntly, but now at Hillside, 52

` Caroline street, South Yarra, both in the State of Victoria,Commonwealth of Australia, (whose post-oilice address is Hillside, 52Caroline street, South Yarra, in the State of Victoria, Commonwealth ofAustralia have invented certain new and useful Improvements inLoose-Leaf Books or Binders, of which the following is a specification.

rl-his invention relates to the class of account or other books havinginterchangeable leaves and commonly lrnown as loose leaf books orledgers. The invention is, however directed more particularly to abinder for books of this class in which the two halves or sections ofthe cover are united by two or more flexible thongs or tapes along whichone of the halves or sections is adapted to be drawn to or from theother section by the operation of a screw mechanism located within themovable section of the cover, this mechanism being externally operatedby a detachable crank handle or key. The advantages of such books havebeen proved but the use of the screw mechanism for separating orcontracting the two halves of the cover is objectionable both on accountof the excessive cost which it entails and also its complexity andliability to derangement. Loose leaf books of a smaller size have alsobeen used in which the two halves of the cover were expanded orcontracted along the tapes by hand and locked in desired p0- sitions bymeans of a ratchet mechanism located within one of the cover sections.This ratchet mechanism is,.however, also open to the objections aboveStated and does not allow of a sumciently tight grip on the leaves ofthe book.

rl`he object of the present invention 1s to eliminate all such windingandv ratchet mechanism and to provide a cheap, simple and eiiicientloose leaf book or binder having all the advantages of the type abovementioned, but at a fraction of its cost. A furtherI object of theinvention is to provide the binding bars of the device with rubber orother linings or faeings having recesses or indentations by which atenacious suction grip is exerted upon the leaves of the boolz. Any lossof power in contracting the binding bars tightly upon the sheets andwhich might be Specification of Letters Patent. Patented Dec. 28, 1920.Application led April 22, 1919.

tions of the cover separated, portions being broken away for convenienceof illustration. The fastening clips which lock the movable section ofthe cover in pre-determined positions on the flexible tapes are shown inlocked position.

Fig. 2 is a longitudinal section of Fig. l

taken in theplane of one of the flexibleV thongs or tapes.

Fig. 8 is a cross section taken on the line A of F ig. l.

Fig. l is a view similar to Fig. 2 but showing thetwo sections of thecover contracted upon a series of leaves or sheets, and the fasteningclip in an unlocked position. The dotted lines show how the tape isbuckled or looped to provide a grip for the hands when the coversections arel being drawn together.

Fig. 5 is an enlarged detail view showing one of the binding barsprovided with gripping strips having cavities or recesses therein.

Fig. 6 is a view similar to Fig. 5 but showing corrugations in place ofthe cavities in the gripping strip. j

Fig. 7 is an'enlarged section taken in the plane of the hinges andshowing clearly how the leaves are held between the gripping strips. Oneof the cover sections is shown closed.

Fig. 8 is an enlarged perspective view of portion of a tubular flexiblethong or tape which may be converted into a round shape.

Fig. 9 is a cross section on line B Fig. 8. Fig. l0 is a perspectiveview of a core used to convert the tape seen in Fig. 8 to a round form.

Fig. l1 shows the tape converted into a round form by the insertion of acore.

Fig. l2 is a fragmentary view showing i portion of a leaf havingelongated eyelets.

Fig. 12T shows portion of a leaf having round eyelets.

Fig; 1li is a sectional view showing clearly how the flexible tapes maybe converted for use with leaves having round eyelets.

On reference to the drawings it will be seen that the numeral 2indicates the front section of the cover and 3 the back section thereof.Att-ached by suitable hinges ll to the rear edge' oi each cover sec-tionis a wooden or other binding bar 6. rlllhese binding bars are lined ontheir inner faces with gripping strips 7 or 7 oi rubber, metal or othersuitable material. Formed in the gripping strips are a series oicavities or recesses 8 seen in Fig. 5 or corrugations 9 as seen in Fig.6. These corrugations do not extend quite to the end ot' the bindingbar.

Suitably fixed to one of the binding bars are the inner ends ot two ormore flexible thongs or tapes 11. These tapes 1l may be ot leather,fabric or other suitable material and are of a comparatively stilinature. They pass througl'i slots or openings 12 formed in the otherbinding bar and thence into channels or slideways 13 formed within thesection 3 of the cover. Part oi each sli'dewa'y is preferably open as at16 to enable the tapes to be gripped when the cover sections are beingdrawn together. Rollers 14 a'nd 15 'are provided to prevent fracture ofthe cover and enable the-tapes to run freely therein.

Attached to the outer ends of the tapes may be metal or other crosspieces 1'? which run in grooves 25 formed at the sides ci the slidewaysand retain the ends oi the tapes in position.

Located within recesses 2O formed in the cover section 3 are metalplates 1S Jirom which upstand bearings 19. ln these bearings are mountedthe trunnions 21 oic a fastening clip which may comprise a inger piece22 formed integral with a right angled holdingpiece 23 adapted to engageand lock the tapes as seen in Figs. 1 and 2.

Preferably, but not essentially, the tastening 'clips are 'connected byarms or extensions 24 to a centrally situated catch 26 so that the:operation of said catch simultaneously operates boththe Afasteningclips. The catch 26 is adapted to engage a suitable lock 2T which may be'provided with a key hole 28 or other suitable means whereby thefastening clips -inay `be locked in a closed position to preventunauthorized insertion or removal of leaves from the book.

The thongs or tapes seen in Figs. 1 to d are in theform shown,particularly adapted for use with leaves 30 having elongated eyelets 29as in Fig. 12. In some cases, however the leaves are provided with roundeyelets such as v3-1 (F ig. 13). The eyelets in each -c'as'e being'entered by `gullets 32. ln Fig. 8

it will be V'seen that the vsides o' tubular tapeare stitched togetherby a series of longitudinal stitches 33. Formed Vat `'cf'invenientintervals in one side of the tubular tapeare holes or slits 34 to admitcores 35.

Should leaves having round gullets such as 31 be used the tapes may beconverted to suit same by cutting the stitches 33 between two or more ofthe holes 34 and introducing one or more of the cores 35 through theholes or slits and into the tape which then assumes a round form as seenin Figs. 11 and 1e. The number of the cores used will depend upon thenumber of sheets to be inserted'in the book as will be fully under`stood on reference to Fig. 13 of the drawings.

ln use the leaves are inserted in the usual manner by entering thethongs or tapes through the gullets 32. Should it be `desired to expandthe two sections of the cover Afor the insertion or removal of leaves.the catch 26 is disengaged from the lock 27' and lifted thereby causingthe fastening clips to be lifted also and releasing the thongs or tapes.rlhe two cover sections are now simply drawn apart by holding thesection 2 or the leaves resting thereon with one hand and pulling thesection 3 outwardly along the tapes with the other. The leaves may nowbe removed or introduced as desired. To contract the halves of the coverand lock the leaves in place. the outer ends of the tapes aremovedtoward the fastening clips so that a loop is formed inthe tape as shownin dotted lines in Fig. e. By grasping this protruding` part of thetapes with the hands and pulling toward the right in the drawings whilethe cover section 3 is held stationary the two sections ot the cover aredrawn' together until the gripping strips are pressed tightly againstthe leaves. The fastening clips are now closed and the catch 23 snappedhome and if desired locked by a key or the like inserted in the hole 28.The slack outer ends of the tapes may be then pushed outwardly along theslideways so that they lie Hat therein as seen in Jfull lines in Fig. 4.

The recesses or corrugations in the gripping strips create a suctionagainst the leaves and cause them to be firmly gripped between thebinding bars.

vIn the draw-ings an open backed binder has been shown but-it will beobvious that if desired a leather `or other flexible back may bridge thespace between the binding bars to cover and protect the back edges-ofthe leaves. This flexible back may be adapted to telescope Vwith-in thetwo sides of the cover in the manner employed in certain known types01:' loose leaf books.

It will be obvious that various modifica-- tions or alterations may bemade in the construction above described without `d'departing V`trom thenature, spirit or scope of the 4invention and it is intended and desiredthat the foregoing description shall be vinterpreted as covering suchlegitimate departures.

What I do claim as my invention, and desire to secure by Letters Patent,is

l. A loose leaf binder comprising two cover sections, flexible means foruniting said sections together on which flexible means one of saidsections is slidably mounted by means of channels or slideways in saidslidable section to accommodate the flexible means, and rollers on theslidable cover sec*- tion over which the flexible means pass.
